如何正确地将InputStream传递给另一个构造函数？(Java)

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;

public class MyClass {
    private BufferedReader reader;

    public MyClass(InputStream inputStream) {
        this.reader = new BufferedReader(new InputStreamReader(inputStream));
    }

    public void processInputStream() {
        try {
            String line;
            while ((line = reader.readLine()) != null) {
                // 处理每一行的内容
            }
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                reader.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}
